IMPR'V'EMENT IN4 COMBINED HARROW AND CULTIVATOR.

The Schedule referred to in these Letters atent and making part of the same.`

To all whom' it fnuvy concern.-

`Be it known that I, HIRAM CULvnR, of Dansville, in the county of Livingston, and State of New York, have invented a new and valuable Improvement in Combined Harrows and Gultivators; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to the letters and figures of reference Amarked thereon.

Figure l, of the drawings is a plan view of my device, and Y Figure2 is a sectional view, showing the eld of one of my cylindrical harrows.

My invention relates to devices intended for use in cultivating corn, and other growing plants; and It consists in constructing and adjusting aV series of cylindrical harows upon a shaft, in such manner that a portion thereof may. be removed, at will, Vto the end that the remaining harrows may be operated as a cultivator. v Y

The letter A, ofthe drawings, represents cart or sulky-wheels, and

, Letter B is thel axle or shaft, upon which they ro` tate.

These lwheels are adinsted onthe shaft for purposes of tlansportation only, and are removed, and washers substituted in their places, when the work ofY harrowing or cultivating is about to commence.4

s The letter C isa frame, consisting of front cross-bar a, side arms b, and lateral arms c, the arms b and c being attached to the shaft Bin the manner shown, and serving as bearings in which said shaft rotates.

,The drivers seat is marked D on the drawings, and is attached to the crossebar ain the manner shown. The lettersvE are a seriesof cylindrical harrows adjusted respectively upon the shaft B by means of the slats s, one of which is attached to each end of the harlows E, as shown on fig. 2, the shaft resting in the openings inthe centre thereof.

The armscpass between these harrows respectively fromthe front cross-bar to the shaft, and serve as removal of alternate ones, allows the operator to draw* the machine over standing rows of corn, and cultivate on eachv side thereof.

If the removal of alternate harrows does not furnish the space required, or adapt the machine to the rows of corn, I remove more or less of the harrows, to suit u the case. l

What I claim as' my invention, and desire to secure A series of cylindrical rotary harrows, adj usted upon a shaft, as described, separated by the arms c, and adapted for the removal of any number thereof, at will,

in the manner represented, and for the purposes herein specified, substantially as described. s In testimony that I claim u the above, I have herelunto subscribed my name, in the presence of two witnesses. l
